Our family of 4 stayed at the apartment for 2 nights. Hosting is managed by a central service and it had all the advantages and inconvenients of this.
Before check-in the communication was OK. We received many automated messages but some of our questions remained unanswered.
For check-in we got the keys from their office. Welcome was professional (they did answer two phone calls while speaking to me) but limited information was available regarding the neighborhood, etc.
The street outside the apartment is nice and typical and has a few restaurants (including a vegetarian one). We managed to park on the street and for now, parking is free.
Arriving at the apartment, everything was spotless clean and the apartment is just like the photos. It was clearly very recently renovated and everything is new. It is, however, furnished very plainly with no real decoration or soul.
We asked for a baby cot and got one. But it wasn't installed, was very dirty and no bed sheets were available. After 3 SMSs and 2 phone calls someone brought bed sheets later in the day. It was a standard set and didn't fit the baby bed at all. The bed sheets for the sofa bed were also a standard set and didn't fit the bed. We had to improvise the bedding when we arrived late in the evening and our two kids were very tired.
There were virtually no bathroom amenities, since only one very small bottle of shampoo was left. At arrival there were no towels for the kids but they were brought with the bed sheets. The kitchen is equipped and functional. While you get a water and wine bottle on arrival which is nice, no capsules for the coffee machine were left, which would have been a nice touch for breakfast.
Location was excellent, only a short walk to downtown, shops and restaurants. Wi-Fi was great too.
All in all it was a OK stay, we enjoyed the location but clearly don't expect any kind of personalized welcome.
Finally, the apartment is not really suited for toddlers since there are unprotected stairs everywhere. We'd probably look elsewhere for our next trip to Porto.
